A liquid crystal display or LCD monitor is a thin, flat device which is made up of a number of pixels arranged in front of a reflector. Each pixel of a LCD consists of a layer of molecules that are aligned between two transparent electrodes. There are also two polarising filters that are aligned perpendicular to each other. When a voltage is applied across the electrodes, a torque aligns the liquid crystal molecules parallel to the electric field. Light can be made to pass through in varying amounts by controlling the voltage applied across the liquid crystal layer in each pixel.
In colour LCD, each pixel is divided into three subpixels which are coloured red, green and blue. Each pixel can be controlled independently to yield millions of colours. High-resolution colour displays use an active matrix structure. In this structure, a matrix of thin film transistors (TFT) is added to the device's colour and polarising filters. When a row-line is activated, all of the column lines get connected to a row of pixels. In this way, all the row lines are activated in sequence.

The active-matrix LCD monitors give more sharp and bright images than passive-matrix displays of the same size. They also have comparatively quicker response time. These displays are considered an important computer accessory as give you high-quality pictures. The displays are widely used in battery-powered electronic devices as they use a very small amount of electric power. The LG's 17 inch monitor measures 365 x 378 x 180 mm. and weighs 3.1 kg. It supports a maximum resolution of 1280 x 1024 pixels with 0.264 mm pixel pitch. The OSD buttons are located on the back panel of the monitor.
LG has launched a range of its newest LCD monitors The LG LCD monitors offer high contrast ratio and superior resolution. These monitors come equipped with LG's unique f-engine picture correction technology. These monitors offer a high digital contrast ratio of 5000:1. The LG LCD monitors have ultra-fast response time of 5Milli seconds. The monitors offer the users a rich multimedia experience. These monitors come equipped with PAL tuner technology that allows them to also double up as a desktop TV. The monitors can also be used for various computing purposes when connected to a PC.
